[PATCH v5 1/3] doc: board: kontron: sl28: Reduce section levels and change title

[Frieder Schrempf]

From: Frieder Schrempf <frieder.schrempf at kontron.de>

In order to add other Kontron boards to the docs alongside the existing sl28 board,
we need to reduce the levels of the sections and change the title.

+Kontron SMARC-sAL28
+===================
 
 The Kontron SMARC-sAL28 board is a TSN-enabled dual-core ARM A72
 processor module with an on-chip 6-port TSN switch and a 3D GPU.

 If this is set, the board doesn't automatically turn on when power is
 applied. Instead, the user has to either toggle the ``PWR_BTN#`` line or
 use any other wake-up source such as RTC alarm or Wake-on-LAN.

 If this is set, the RCW will be fetched from the on-board eMMC at offset
